TU'BULAR FABRIC AND METHOD OF WEAVING THE SAME.

Specification of Letters Patent.

Patented March 9, 1909.

Application ied June 1, 1908. Serial No. 435,959.

To all whom 'it may concern:

Be it known that I, EMIL KUNZLI, a citizen of the United States, and aresident of the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful improvements in TubularFabrics and the Method of l/Veaving the Same, of which the following isa specification, reference being had to the accompanying drawings, inwhich- Figures 1 to 10 inclusive are diagrammatic representations of thewarp threads showing the successive passage of the shuttle in order toform my improved fabric; Figs. 1a to 10al are corresponding crosssectional illustrations; Fig. 11 is a central longitudinal elevation incross section showing the construction of my improved fabric togetherwith the woof threads, the opening between the upper and lower crosssectional illustrations being the central opening of my improved tubularfabric; Fig. 12 is a view in central cross section of part of Fig. 11,showing a modified form of inserting a double series of short binders;Figs. 13 to 15 inclusive show sectional views of my irnproved fabric,illustrating particularly the mode of inserting the woof threadsthroughout the several cycles necessary to form the complete tubularfabric.

Similar letters and numerals refer to similar parts throughout theseveral figures.

Frequently heretofore in the construction of multiple ply tubularfabrics, the sheds of woof threads are successively introduced andinterwoven into the fabric during the process of weaving and are eachindependently interwoven with a corresponding set of warp threads of theseveral sets required for the weaving of such tubular fabric. Suchmethods of weaving cause one set of warp threads to be raised while thesuccessive sets are depressed during the passage of he woof threads informing such ply or strata of the fabric and such process is carried on,forming what is known in the trade as a plain weave. The density of thewoof sheds or their relative proximity to one another is measured by thenatural resistance of the opposing' warp series at each intersection,and in order to obtain the highest possible degree of density it hasheretofore been the practice to drive the woof threads as closely aspossible, whereby the indentations caused to the woof threads, at

their intersection with the warp threads are substantially at rightangles with each other. By such methods the resisting qualities of thetubular fabric, or the strains put upon such fabric when a heavypressure is eX- erted within the walls of the fabric, are necessarilyborne chiey by the series of superimposed strands of woof threadsforming a series of rings, one superimposed over the other so that themaximum degree of resistance in the fabric is measured by the tensilestrength of the woef threads. Such woof threads, therefore, should befree from entanglements, and it is apparent that when these woof threadsare intersected and held by the action of the opposing warp threadsAunder pressure certain structural displacements between the warp threadsand the woof threads are inevitable, whereby a friction under theincreased pressure is likely to become a direct cutting action betweenthe warp threads and the threads of the strands of woef threads directlyin contact with each other. Such action or friction between suchopposing threads constitutes an inherent weakness of such tubularfabric.

he object of my invention, among other things, is to construct a tubularfabric so as to do away with the transverse cutting action between thesets of woof threads and warp threads heretofore described, and in sodoing I form atubular fabric so as to obtain the maximum degree oftensile strength of the superimposed woof strands to an interiorpressure, and at the same time obtain a density of the woof or fillinginterwoven in the fabric sufficient to insure water tightness, at thesaine time eliminating the friction or the water iiow under pressure sothat I am enabled to dispense with the customary rubber lining on theinside of my tubular fabric without any perceptible increase of frictionor diminution of water pressure caused by the flow of water underpressure through my tubular fabric.

In order to accomplish my invention l construct what is known as amultiple ply woven tubular hose fabric having a series of independentlyoperated warp threads which are constructed during the process ofweaving to form what is known as a three leaf twill warp formation,constituting the inner wall of my improved fabric, and a similar' seriesof warp threads forming a similar' three leaf twill to constitute theouter wall or covering of my improved fabric, each of which linings orcoverings constituting the t-hree leaf twill are operated independentlyof each other by a separate set of three heddles.

During the process of weaving' my said tubular fabric I arrange betweenthe inner wall or lining and the outer covering' a series oflongitudinal threads in pairs which I term padders preferably having thesets of contiguous threads arranged so that the twist in such threadsshall be toward each other; in other words that the twist of one threadshall be toward the right while its adjoining contigious thread willhave its twist toward the left. Such threads are sometimes termed idlerthreads. I construct my tubular fabric by having these so-called padderthreads inserted between the inner lining and the outer covering, andprefer to have a double set of the same separated from each other by thecentral series of woof threads, and connected and intermeshed with theinner lining or outer covering by a series of threads which I havetermed long binders that run longitudinally through my tubular fabricand are interwoven with the outer covering on the one side and the innerlining on the other, such long binders being' alternate, and do not, ineither case, reach the outer or inner surface of 4my tubular fabric.

In order to give greater strength and to insure a more perfect unionbetween the woof threads interwoven with the three leaf twillconstituting the inner lining of my tubular fabric and the next seriesof woof threads adjacent to the first series of padder-s next to theinner lining, Iprovide a series of binding threads running along` thelength of my tubular fabric which intersect and bind together the firstseries of woof threads which are intermeshed with the three leaf twillforming' the interior lining, with a second series of woof threads whichsurround the first series of padder threads. These I describe as shortbinders.

Referring now to the drawings, Fig. 1 represents, as heretofore setforth, the set of 22 series of warp threads, which go to make up thefirst form or position of such threads at the initial movement of theshuttle when the pick is about to make the first interweaving of thewoof threads in constructing my fabric. Beginning at the center, a', a2,a3, denote the three threads forming the three leaf twill of the innerlining on the under side. b', b2, 53, are a like series of three warpthreads forming a similar three leaf twill for the inner lining on theupper side. 0 is a warp thread of short binders binding the under innerthree leaf twill pick to the next superimposed pick of the under part ofmy tubular fabric. Z is a similar warp thread lconstituting a shortcarried on the under tubular section without being interlocked with thepicks. f and f2 are padder threads on the upper side of my tubularsection, likewise not being interlocked with the picks. g and g2 are thewarp threads on the under tubular side forming what I term the longbinders, alternating and binding and interweaving the superimposed picks52, 3, 4 and 5, etc. of the lower tubular section. hf, are correspondingwarp threads which I have termed long' binders alternating and bindingtogether 'with the superimposed picks 2, 3, 4, 5, etc. of the uppertubular side. j, jg, y'i, are three warp threads interwoven so as toform the outer three leaf twill of the outer covering of 'my tubularfabricl on the under side. 7a2, 7c3, are corresponding warp threadsforming the three leaf twill of the outer covering on the upper side ofmy improved fabric. and specification, letters represent warp threadswhile numerals denote woof threads. It will be observed that the upperedges of these warp threads constitute the three leaf twill of the innercovering, being the warp threads a, a2, a3, and the warp threads b', b2,3, are so arranged at the beginning of my weaving' process that theyform a perfeet union in the construction of thethree leaf twill formingthe inner lining of my improved fabric. So likewise the outer series ofwarp threads y, jg, jg, and 7c', 7:2, 71:3,

are so arranged at the beginning of my Throughout the drawings.

weaving process that they form a perfect union in the construction ofthe three leaf twill forming the outer covering of my improved tubularfabric with the exception ofV the action of the binding threads whichwill hereafter be described. So also the padder threads e, e2, f, f2,are arranged so as to form a continuous union at their outer edges asthe process of weaving proceeds.

1 and 2, in Figs. 1 and 1, show the movement of the pick or shuttleduring the first step in my process of inserting the woof threads in mytubular fabric'.

In Figs. 2 and 2a, 3 and 4 show the second step in my process, being adiagrammatic representation of the changed relation in the various warpthreads and the operation of the pick or shuttle in the second step inweaving' my improved fabric, in order to form the three leaf twillconstituting the inner lining and outer covering' of my fabric as wellas the intermeshing of the binder threads.

Figs. 3 and 3 show the third step in my process of weaving my improvedfabric and 5 and 6 show the passage of the shuttle or pick interweaving'the woof threads in such step or process, and also illustrating thechanged relation of the various woof threads constituting the three leaftwill of the inner lining and outer covering, as well as the action ofthe binding threads.

Figs. d and da show the fourth step in my process of weaving my improvedfabric and 7 and 8 show the passage of the shuttle or pick ininterweaving the woof threads and the series of warp threads shown inthe figures.

Figs. 5 and 5a represent the fifth step in ny process of weaving myimproved fabric and 9 and 10 show the passage of the sluittle or pick ininterweaving the woof threads with a series of warp threads shown in thefigures. This fifth step in the process of weaving my improved fabriccompletes the first cycle, and it will be observed that the shuttle orpicks 9 and 10 have carried the woof threads so as to intermesh betweenone of the threads forming the outer three leaf twill on the inside andthe other two warp threads forming the three leaf twill of the outercovering together with one of the lang binders.

G and 6a represent the return movement of the shuttle or picks 11 and 12in which the passage of such shuttle discloses on the outside two of thewoof threads forming the three leaf twill of the outer covering with thesecond long binder and on the inner side the warp thread of the threeleaf twill forming the outer covering which was formerly on the outersurface of my tubular fabric, all of which is fully shown in thediagrammatic and cross sectional views of such warp threads.

Figs. 7 and 7 a, Figs. 8 and 3a, Figs. 9 and 9u and Figs. 10 and 1()show the passage of the shuttle or picks 13 and 14 respectively, 15 and16 respectively, 17 and 13 respectively and 19 and 2O respectively inthe re-y verse order as shown in Figs. 1 to 4t and 1a to la inclusiveheretofore described. These Figs. 7 to 10 inclusive and 7a to 10ainclusive represent in diagram and cross section the various warpthreads heretofore described, and illustrate clearly in the method ofweaving my improved tubular fabric the passage of the woef threads so asto complete the cycle necessary to form my improved fabric which, asshown in the drawing, consists in a five ply series of woof threads.

Referring` to Fig. 11, this view shows, in an enlarged cross sectiontaken longitudinally, my tubular fabric as completed, the same lettersreferring to the same warp threads and the numbers 1 to 30 inclusiveshowing the woof threads as they exist in my fabric, such woof threadsreferred to numerically being the same as shown in the picks or shuttlesheretofore described in connection with Figs; 1 to 10 and 1a to 10@linclusive. l have also shown by c3 and c* and f3 and ft at either end ofFig. 11 the relative position of the padder threads having the reversetwist adjoining the padder threads c, e2, f', f2, respectively, suchreverse padder threads c3, c4, and f3, f4, being turned up at the end,so as to show the insertion of the long binders g', g2, and 7L', h2,respectively between such series of padder threads. ln Fig. 11 therelation of such long binders to the constituent fabric is clearlyshown; likewise the relation and action of the short binder threads cand d.

1n Fig. 12 a modified form of a method of inserting the short binderthreads c and Z is illustrated, whereby a second short binder thread d,c', may be inserted so as to combine the two inner series of woofthreads 2, il, 18, 20, 22, 24, etc. as shown in the drawings.

Figs. 13, 111 and 15 are, as heretofore described, cross sectional viewsof my improved fabric, showing by the round dots the various series ofwarp threads that constitute my fabric as shown in Figs. 1 to 10 and 1ato 10"l inclusive, together with the double line which shows indiagrammatic form the passage of the shuttle from the initial passageshown in Fig. 13 where the pick enters and carries the woof thread so asto form the first series of inner woof threads and thereafter proceedingand intermeshing with the various warp threads as heretofore shown inthe diagrammatic figures through five revolutions, where it finallyemerges at the outer covering of my fabric and then passes to Fig. 14;where the reverse operation is pursued so that after five circularpassages of the shuttle the picks emerge at the inner lining of myimproved fabric and then pass on down to Fig. 15 which illustrates thethird cycle and passage of the shuttle carrying the woof threads throughtive revolutions until it emerges at the outer covering of my tubularfabric, and then the shuttle will pass through the same movements asshown in Fig. 14 and then, as shown in Fig. 13, completing the entiremovement of the shuttle carrying the woof threads so as to finallycomplete and constitute a tubular fabric such as is shown entire inlongitudinal cross section in Fig. 11.

1n Figs. 13, 111- and 15 the numbers 1 to 20 inclusive show the Woofthreads as carried by the shuttle, such numbers corresponding to thenumbers shown in Figs. 1a to 10a inclusive by the dotted lines, and suchwoof threads are also shown in cross section in Fig. 11. 1n Figs. 1 to10 inclusive, the numerals which are primed, as for instance 1, 2', 3,l1, etc., illustrate the sheds where the shuttle carries the woofthreads through the warp threads illustrated in Figs. 1 to 10 inclusive,such sheds having the same number as the pick which passes through, asfor example pick 5 passes through shed 5 and pick G through shed 6.

It will be observed from the construction of my tubular fabric that therelations between the various threads constituting my fabric permits theclosest possible packing between the various series of woof strandswhich go to make up my multiple ply fabric, the action of the binderstending to hold such woof strands closely together, and also,

when my fabric is in use, as for instance during the passage of waterunder pressure, such pressure, being exerted outwardly, will also tendto pack still more closely the various plies of woof threads, while thethree leaf twill formation, which I use for my inner lining, as well asouter covering, from its very construction tends to prevent the increaseof diameter of my fabric or swelling of such fabric from interiorpressure, the only tendency of such three leaf twill being to create asmooth surface. The insertion of the padder threads heretofore describedprevents the stretching` of my fabric, and in order to reduce thefriction on the inner lining I may soak such three leaf twill threads,prior to the formation of my fabric, in paraffin or oil, so as tominimi-ze the friction incident to the passage of water under pressurethrough my fabric.

rThroughout the foregoing specification I have referred to the exteriorcovering and inner lining, as being of the three leaf twill formation,but I do not wish to confine myself to this particular form of weave,for a four or even five leaf twill may be employed in the constructionof my tubular fabric, with the same effects and advantages.

Instead of having a single continuous woof thread to form the multipleplies of my fabric I may'also use two shuttles thereby interineshingwith the various series of warp threads, two continuous woof threads,one forming the multiple plies by ruiming concentrically through thefloating warp thread of the inner lining, and the short binders, whilethe other woof thread intermeshes the short binders the padder threads,and the float-ing warp thread of the exterior covering.
